Abstract

It is becoming increasingly apparent that the metabolism of the phosphoinositides catalysed by phosphoinositide (PI) 3-kinase has signal-transducing consequences that rival those of phosphoinositidase C activation in a variety of cells. Phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3) is a major cellular product of agonist-activated PI 3-kinase and has therefore been proposed to act as a second messenger; thus suggesting the existence of an in vivo PtdIns(3,4,5)P3 receptor. It is towards purifying and characterising this putative PtdIns(3,4,5)P3 receptor that this proposal is aimed. Experimentally, it is proposed to use [32P]inositol 1,3,4,5-tetrakisphosphate (Ins(1,3,4,5)P4)-binding to follow purification, since chemically PtdIns(3,4,5)P3 has Ins(1,3,4,5)P4 as its polar headgroup.
